IMPROVEMENT SLIVER-GUIDES FOR CARDlNG-MACHINES.

Specification forming part of 'Letters Patent No. 34,50S, dated February 25, 1862.

To all whom, it may concern.'

Be it known that I, HERVEY KENT, a citizen of the United States of America, and a resident of Lewiston, in the county of Androseoggin and State of Maine, have made a new and useful invention or improvement having reference to the adjustment of the sliver-guide of a carrying-trough employed incombining slivers from carding-engines; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure l denotes a top view of a sliverguide and its trough (in part) as provided with my invention; Fig. 2, alongitudinal section of the same; Fig. 3, a view of the under side of the guide-plate. Fig. 4 is a top view of the trough-opening for the reception of the guide-plate.

The nature of my invention consists in a peculiar application of a sliver-guide to a sliver-carrying trough or carrier, whereby the guide is rendered capable of being movedv across the carrier in a circular or curved path, substantially as and for the purposes as hereinafter explained; also in the application of annular ranges of teeth (or their mechanical equivalents) to the guide-plate and the trough and so as to enable the adjustment and retention of the guide in position relatively to the carrier or surface beneath it to be effected substantially as hereinafter described.

In the process of producing a larger sliver from a series of smaller ones delivered, respectively, from several carding-engines it is customary to run all the lesser slivers into one trough and upon a carrier-carriage or endless traversing belt contained and workin g within such trough. It is an object to spread the products of the several carding-engines as evenly as possible and in correct positions on the carrier, in order that a united sliver having a uniform thickness and width may be produced.

It has been usual to have the sliver guide or hole of the cover of the trough of the carrier either stationary or movable. Vhen movable, it has been in a slider so adapted to the box or trough as to be capable of being moved either straight or diagonally across it, in which case,in order to have the opening in which the slider must of necessity be placed always closed by the slider, except at its sliver-passage, it has been requisite to make the slider so long that on adjusting it it would frequently project beyond the trough in a manner to be more or less in the way of persons or objectionable otherwise. Such projection beyond the vtrough is avoided by my improvement or invention, as in no case during adjustment of the sliver-guide will its plate project over the side of the trough, but remains always in the same place. more, my invention aifords good facilities for readily adjusting all the slivers of a vseries Whenever it may be desirable to stop any one of the carding-engines, whetherfor repair or any other cause.

In the drawings,A denotes the sliverlguide as fixed to or combined with a circular disk or plate B, which is separate from and covers a circular opening C, made in the top plate a of the trough D, through which a carrier or endless belt G may be supposed to run in the position shown in Fig. 2. F is one of the presser-rollers of the carrier. The diameter of the opening C is about equal to the width of the carrier, in order that by simply turning the plate B around while covering the opening C the sliver passage or guide A may be moved in a circular or curved path and be adj usted widthwise of the carrier and so as to cause a sliver while being led through the guide to be deposited on such part of the carrier as it may be desirable to have it laid.

The circular disk B should be made with its diameter somewhat larger than that of the opening C, in order that the disk may be supported on and by the top plate of the trough.

The under side of the disk, as well as the edge of the opening C, I provide with a circular range of teeth b b b or c c c, as shown in Figs. 2, 3, and 4, and each tooth of the one portion corresponding in size with each space between two adjacent teeth of the other. Vhile the ranges of teeth are in engagement with one another they serve to prevent rotation of the disk and displacement of the guide, the disk being kept down upon the trough by means of two clamp-screws h h, formed and arranged as shown in the drawings.

It will be seen that while the guide A is in Furtherany position over the carrier tl1e`plate B not only completely covers the opening C, but does not inconveniently project beyon d either edge or side of the trough.

My invention and what I claim consistsl. In the application of the sliver guide o1` hole A to a carrier G or its trough by means of a circular plate B or its equivalent, so as to be capable of being moved across the said carrier 011 trough, as the case may be, in a circular or curved path, substantially as and for the purpose of attaining results as above set forth.

2. The combinationof the circular ranges of teeth b b b c c c, 0r their mechanical equivalents, with the guide-plate B and the trough thereof, the same being arranged for the pur pose and to operate substantially as hereinbefore specified. i i
